Channels 3 and 4 cannot be assigned in the same market because they 
are actually adjacent frequencies.  Channels 4 and 5 are not actually 
adjacent, there is a 4 MHz gap between them, used for other purposes. 
I believe the gap frequencies (72 - 76 MHz) were originally used for 
land-mobile services, I'm not sure what they're used for today, if 
much at all, but I'm sure someone on the list will supply the answer.
